Chemical Engineering Gate 2016 Questions with Answer

Ques 27 GATE 2016

Water flows through a smooth circular pipe under turbulent conditions. In the viscous sub-layer the velocity varies linearly with the distance from the wall. The Fanning friction factor is defined as f = τ_w / (ρ U_avg² / 2) where τ_w is the shear stress at the wall of the pipe, ρ is the density of the fluid and U_avg is the average velocity in the pipe. Water (ρ = 1000 kg m^-3, μ = 1×10^-3 kg m^-1 s^-1) flows at an average velocity of 1 m s^-1 through the pipe. For this flow condition, the friction factor f is 0.005. At a distance of 0.05 mm from the wall of the pipe (in the viscous sub-layer), the velocity (in m s^-1, rounded off to the third decimal place), is ______?

Ques 33 GATE 2016

Students taking an exam are divided into two groups, P and Q such that each group has the same number of students. The performance of each of the students in a test was evaluated out of 200 marks. It was observed that the mean of group P was 105, while that of group Q was 85. The standard deviation of group P was 25, while that of group Q was 5. Assuming that the marks were distributed on a normal distribution, which of the following statements will have the highest probability of being TRUE?
